The Coronavirus pandemic has the entire world in turmoil – public spaces locked and whole nations in lockdown. Despite the pervading sense of gloom, there is indeed a silver lining. Recently, there have been plenty of news reports on how nature is resetting itself without the intervention (and pollution) caused by humans. The lockdown due to the COVID-19 pandemic is not only keeping people safe indoors but is also giving the outdoors much-needed time to recharge. A recent example is the canals in Venice that are looking clearer and cleaner now, due to the absence of the famed Italian gondolas that ply tourists on the waterways every day. Generally, the tourist boats plying the Italian canals bring the sediments to the top. With the absence of the boats, the water looks clearer and cleaner now. Not just the water, air quality has increased significantly in Venice. Not only in Venice, but different regions all across the world are also reporting vast improvements in air quality. Closer home, the waters of the Yamuna is turning cleaner thanks to a significant reduction in pollution. Generally, the waters of the Yamuna river is highly polluted due to various activities like – throwing of worship flowers, garlands, and other religious materials, soaps used by people bathing in the waters of the Yamuna and industrial effluent from industries and factories located on the shores of the river. The local residents believe that the closure of factories along the Yamuna belt is a significant reason for the river water turning clean.
The Need of the Hour in the War against Corona – Access to Clean Water
As the world confronts the Covid-19 pandemic, medical experts agree that the best ways to minimise the odds of catching the virus are by maintaining social distancing and washing hands thoroughly and frequently with water.
But, one of the biggest concerns facing our planet is – lack of access to clean water. World Water Day is celebrated on the 22nd of March every year. The UN uses this day to highlight the need for providing clean water to everyone on the planet for drinking and sanitation purposes. Over the last few decades, there have been plenty of revolutionary technologies for treating wastewater.
Water is one of the most precious commodities on the planet. It’s used for drinking, sanitation, for growing food, and for numerous industrial processes. While water treatment technologies have increased rapidly over the years, even today more than 40% of the world’s population live in water-scarce areas, and nearly 1000 children worldwide die from sanitation and water-related diseases, all of which can be prevented.
Since the 1980s, water usage has increased globally by 1% every year due to changing consumption practices, economic development and rising population. Added to these problems, water bodies all over the world are threatened by overuse, climate change and pollution.
Just last year, the residents of Chennai faced one of the most severe water crisis in recent times. Residents had to queue up for water supplied by tanker trucks. Empty reservoirs, droughts, exhaustion of groundwater supply all compounded to the water crisis faced by the southern city. Not just Chennai, the water problem is present in several regions, and countries across the world include rural Mexico, South Africa and more.
Today with the Coronavirus spread across all continents except Antarctica, washing hands with clean water is a major challenge for several developing nations.
Zero Liquid Discharge – An Innovative 100% Water Recycling Process
ZLD (Zero Liquid Discharge) is a unique water treatment process that industries and factories can use to purify and recycle water with zero discharges. It’s an advanced water treatment process that uses various techniques like reverse osmosis (RO), ultra-filtration, crystallisation, evaporation, and more.
Industries like oil, gas, power, petrochemical, paper manufacturing, food processing, etc. generate large volumes of water that can (and must) be managed. Generally, most industries let out their wastewater into an evaporation pond or deep wells. However, this is not the most environmentally friendly disposal mechanism.
The Zero Liquid Discharge system can help in the maximum recovery of wastewater making it available for reuse.
At Sintech, we offer thermal and non-thermal Zero Liquid Discharge solutions to help industries treat their wastewater with zero environmental impact. We make use of brine concentrators, evaporators and crystallisers to help you recover 95% of the wastewater generated in your plant. The remaining is converted into solid brine. We choose the pump systems depending on the viscosity of the wastewater.
